Laplace-Carleson embeddings and infinity-norm admissibility

Birgit Jacob, Jonathan R. Partington, Sandra Pott +2

A full characterization of the boundedness of Laplace--Carleson embeddings on $L^{\infty}$ is provided, in terms of the Carleson intensity of the respective measure and of a suitable…

A sharp higher order Sobolev embedding

Raul Hindov, Shahaf Nitzan, Jan-Fredrik Olsen +1

We obtain sharp embeddings from the Sobolev space $W_{0}^{k, 2} (- 1, 1)$ into the space $L^{1} (- 1, 1)$ and determine the extremal functions. This improves on a previous estimate of the sha…

On Dirichlet-type and $n$ -isometric shifts in finite rank de~Branges--Rovnyak spaces

Shuaibing Luo, Eskil Rydhe

This paper studies the function spaces $D (I^¼)$ by Richter and Aleman, and $D_{I^¼}$ by the second author. It is known that the forward shift $M_{z}$ is bounded…
